They talk to each other over UHF for the location tracking. So if you’re out on the same channel (but not on a Rhino) then you get a squalk tone every few mins. Pisses me off
I don’t have much info for you Simmo but take a look at Shonky Maps. They are free topo maps for the older Garmins so I’d be surprised if they didn’t work with the newer ones too. I’ve used them for over 10 years and they’re great!
They’re fantastic!! Well done!
I’m amazed at how well the wood took the die. Did you just sit the wood in a bath of it for a time or did you have to force it in under pressure somehow?
